SPECIFICATION formingpart of Letters Patent No. 662,864, dated November27, 1900.

Application filedNoveniber 20,1899. Serial No. 737,651. momma.)

To all whom it may concern:

Be it known that I, EDWARD HETT, a citizen of the United States, and aresident of New York, (New Dorp,) county of Richmond, State of New York,have invented certain new and useful Improvements in Machines for MakingPrinting-Surfaces, of which the following is a specification.

Thisinvention relates to machines designed for use in makingprintingsurfaces, and more particularly to machines adapted to beemployed to impose a design or plurality of designs upon a printing-formadapted to be transformed into a printing-surface for the design ordesigns. The printing-form when completed may be either planographic,relief, intaglio, or other character.

Theinvention seeks, among otherthings, to combine in one machinemechanism whereby a design or plurality may be imposed from a setting-up plate or other basic surface upon a printing-form and mechanismwhereby the design or designs so imposed upon said printingform may beimposed upon a second printing-form. For convenience the firstnamedprinting-form will be herein termed the primary printingform, and whendeveloped into a printing-surface it will be termed the primaryprinting-surface. The second-mentioned printing'form will forconvenience be termed the secondary printingform and when developed intoa printingsurface the secondary printing-surface. In the preferredconstruction the design or designs are communicated from the primaryprinting-surface to a suitable conveying-surface and are thencommunicated from the conveying-surface to the secondary printingform.The invention, however, includes Within its scope an arrangement wherebythe design or designs of the primary printing-surface may becommunicated directly to the secondary printing-form without theintermediation of a conveying-surface.

In addition to the mechanism above referred to the invention also seeksto provide means whereby the design or designs of the setting-up plateor other basic surface may be imposed upon the primary printing-form inaccurate predetermined position and a means whereby the design ordesigns may be then communicated to or imposed upon the secondary formin accurate predetermined position and with reference to register in theultimate use of the secondary printing-surface in its operation ofprinting. The secondary printing-form is preferably constructed ofpredetermined size and shape, so as to accurately fit in apreestablished seat in the machine or transfer-press and in apreestablished seat in a printing-press. Itis removable from andreplaceable in said seats, so that othersecondary printing-forms may bemounted in said seats and accurately fit and Work with the cooperatingparts of said presses.

The printing-forms are preferably curved, so as to work in a rotaryprinting-press, and they are also preferably shell-like,cylindrical, andtubular. The primary printing-forms are preferably constructed so as tobe identical in size and form with the secondary printingform and so asto be removable from and replaceable in a preestablished seat in thetransfer-press and so that other primary printingforms may be mountedaccurately in the same seat in such press. Of course it is not essentialthat the primaryprinting-forms shall be made so as to fit apreestablished seat or seats in a printing-press unless such forms areto be used in printing. It will be most economical, however, to soconstruct them with reference to a printing-press.

The basic surface or setting-up plate is constructed to accurately fitin a preestablished seat in the transfer-press and is removable from andreplaceable therein. The conveying-surface is also preferably removableand replaceable in a preestablished seat in the transfer-press, and inthe simplest construction the same seat is employed for the basicsurface and forthe conveying-surface. Both the basic surface and theconveying-surface,

or either of them, might with some advantage be permanently mounted inthe transfer-press, and such arrangement is within the scope of myinvention. The basic surface and conveying-surface are both preferablyflat and mounted upon a horizontal reciprocating bed or beds, theprimary and secondary forms Working by rolling contact With saidsurfaces. The invention is not limited,

however, in its broad aspect to a basic surface which is flat orreciprocating nor to a conveying-surface which is fiat or reciprocating.

Either or both of these surfaces may be curved, and either or both ofthem may r0- tate or be stationary. The invention is not in its broadscope limited to any particular form or shape of basic surface, ofconveyingsurface, of primary printing-form, or of secondaryprinting-form, nor is it so limited to any particular character ofmovement of these features in the operation of imposing a design ordesigns from one to another.

In the accompanying drawings,which form part of this specification, Ihave illustrated a machine embodying the various features of theinvention in their preferred form and also modifications.

Figure 1 is a side elevation of the machine in its preferred form. Fig.2 is a central longitudinal section of the machine shown in Fig. 1. Fig.3 is an end elevation lookingiu the direction of the arrow in Fig. 1.Fig. 4 is a plan view showing the basic surface detached from themachine and mounted in its preestablished seat on the bed. Figs. 5 and 6are respectivelyside elevations of asettingup plate andconveying-surface. Figs. 7and 8 are central longitudinal sections ofmodified forms of the machine. Fig. 9 shows a detail in section.

Referring now to the specific mechanism shown in the drawings, andparticularly to Figs. 1, 2, and 3, the machine is provided with asuitable and substantial frame 1, which may be of any approved design,and on this frame is a bed or support 2, having thereon a removable andreplaceable basic surface 3, preferably including a zinc or equivalentsetting-up plate or transferbase having fixed thereto the design ordesigns to be imposed upon, imparted,or transferred to the primaryprinting-form. The transfer-base in its best form is non-expansible anduon-contractible, so that the design or designs fixed thereon are alsonon-expansible and non-contractible under the pressure of the printing,and thus the design or designs may be imparted to the primary printing-form. The transfer-base is generally of such thickness as to form arigid body, as shown. It has one side and one end made perfectly true,so as to accurately fit in the preestablished seat formed on the bed 2,which seat is determined by the ribs 4 and 5, against which the basicsurface is forced by the nuts 4 and 5. The ribs 4 and 5, it will thus beseen, constitute guiding means, with reference to which the basicsurface may be brought both longitudinally and transverselyinto thepredetermined position required or the preestablished seat. The designor designs of the basic surface are generally fixed thereto by beingprinted upon several transfer-sheets stuck up on the transfer-base after.the lithographic manner. If desired, instead of always using the sametransfer-base a series of transfer-bases may be employed and soconstructed as to fit accurately in the same preestablished seat on thebed 2.

The bed 2, which is flat, as shown, recipro cates horizontally in theslideways 6, formed on the frame of the machine, being driven by therotating screw-shaft 7, which-passes through the threaded nut 8, fixedto the bed. The screw-shaft 7 is driven in one direction to move the bedforward and in the opposite direction to move the bed backward bysuitable mechanism. In the present instance I employ a main drive-shaft9, on which is fixed a gear-wheel 10, geared to the motor 11. On theshaft 9 is a gear-wheel 12, meshing with the gear-wheel 13, fast on thescrew-shaft 7. The gear-wheel 12 is locked on the shaft 9 and unlockedtherefrom by the clutch 1i, operated by the shaft 15. This shaft carriesa clutch-operating arm 16 and also arm 17, having a slot which receivesa pin carried by the hand-shaft 18. By operating the shaft 18 the wheel12 maybe locked and unlocked with respect to the shaft 9. The motor 11is reversed to reverse the screwshaft 7.

19 is a primary printing-form carried on the support 20 and from whichit is preferably removable and replaceable. In its best form the primaryprinting-form is continuous, cylindrical, and tubular in form, thesupport being in the form of a hollow cylinder and body removable andreplaceable on the shaft 21, on which it is locked in place. The primaryprinting-form 19 is shell-like, as shown, and is provided with ribs 22on the under side, which are adapted to enter corresponding recesses inthe support 20, a marked rib in a marked recess, when the printing-formis slipped onto its support. The supporting-cylinder 20 is provided witha circumferential shoulder 23, against which the printing-form isadapted to accurately lit and against which it is pressed home and heldby the clamps 24. The shoulder 23-and the ribs 22 constitute guidingmeans, with reference to which the primary printing-form and successiveprimary printing-forms may be located accurately both longitudinally andtransversely in a preestablished seat on the support and always in thesame pre determined position. Any other forms of guiding means for thispurpose may of course be employed.

The shaft 21, which carries the form-support 20 and the primaryprinting-form 19, is movable up and down, so that the primaryprinting-surface may be brought into contact with the basic surfaceunder suitable pressure and so that it may be moved out of contact withthe basic surface. For this purpose the shaft 21 is carried in thevertically-moving bearings. One of these bearings (shown in dotted linesin Fig. 2) is an ordinary square box movable in the slideway 25 on oneside of the main frame. This box is connected with the pressure-arm 26.The other hearing is provided by complementary semicircular recessesformed in the arms 27 and 28, pivoted on the horizontal pivot 29, fixedon the sliding frame 30.

The arms 27 and 28 move up and down behind the keeper-plate 31 on ashaft 32, which is fixed on the main frame and is provided with aworm-gear 33, operated by the worm-shaft 3 1. When the keeper 31 isdown, as shown in Fig. 1, the arms 27 and 28 are thereby held firmlytogether against the main frame and in an up right position. The arms 27and 28 constitute a pressure-arm corresponding to the oppositepressure-arm 26. The shaft 35, worked by the hand-lever 36, carrieseccentrics 37, which operate the pressure-arms. The main frame on theside of the arms 27 and 28 has an opening 38 large enough to permit thepassage therethrough of the primary printing-form 19. When theprinting-form is to be removed from the machine, the keeper 31 is movedupward outof the Way of the arms 27 and 23. These arms are swungdownward on the pivot 29. The cylindrical printingform 19 is thenslipped from the supportingcylinder 20 through the opening 38. Inremoving the printing-form 1 generally employ the apparatus shown anddescribed in the patent granted to me November 21, 1899, No. 637,579,said apparatus being provided with an arm adapted to be held in fixedalinement with the shaft 21, so that the printing-form 19 may be slippedfrom its supporting-cylinder upon said arm. The printing'form 19 isequipped with inking and dampening devices, whereby the printing-form isrolled up in the operation of developing it into a printing-surface andwhereby the primary printing-surface 19 may be inked for the purpose ofcommunicating its design to the secondary printing-form.

39 is the main ink-distributing cylinder, fixed on the shaft 40 andcommunicating ink to the printing-form 19 through the usualinkdistributing rollers, which are carried'in the swinging frame 41,supported by the shaft 10. A hand worm-shaft 42 operates the shaft 13,which carries gears 14:, meshing with segmental gears 15, formed on theswinging frame 41. By operating the handshaft 42 the frame 11 may bemoved so as to carry its inking-rollers to and from the primaryprinting-form 19.

' 16 is a sliding frame carrying dampeningrollers 47 and operated by theeccentric-shaft 4L8, whose eccentrics 49 turn in boxes formed in theframe t6, the shaft being operated by the hand-wheel 50.

51 is a gear-wheel working on a stud fixed on the inside of the mainframe and meshing with the gear 52 on the main distributingcylinder 39and with the gear 53 on the formcylinder 20, so that the form-cylindermay be driven from the ink cylinder 39. Movement is communicated to theinking-cylinder 39 from the main shaft 9 by the Worm-gear 5 1, meshingwith a gear 55 on the shaft 56, which carries a gear 57, meshing with agear 58 on the vertical shaft 59, which carries a beveled gear 60,meshing with a beveled gear 61 on the shaft 10. The worm 54 is formed ona rollers 73.

sleeve adapted to be locked on and released from the main shaft 9 by theclutch 62, operated by the shaft 63, which itself is actuated by thehand-shaft 64.

In order that the basic surface may impose its design or designs uponthe primary printing-form in accurate predetermined position, the bed 2is provided with a tooth 65, designed to mesh with a marked recess inthe gear 53. When the basic surfaceand primary printing-form arecoiiperating, the printingform is lowered, so that the tooth 65 entersthe marked recess, and thus the basic surface and printing-form may bebrought into an accurate predetermined cooperating relation, whichrelation may be repeatedly obtained with the same or different primaryprintingforms and with the same or different basic surfaces. The tooth65 and marked recess constitute preestablished guides,whereby thispredetermined relation may be attained.

In the embodiment of the machine shown in the drawings the secondaryprinting-form 66 is constructed, arranged, and mounted in identicallythe same way as the primary printing-form 19 and is equipped with inkingand dampening rollers of the same construction and arrangement as thosefor the primary printing-form. Only a brief reference to the secondaryprinting-form and its inking and dampening rollers will therefore berequired. The secondary printing-form has ribs 67, whichentercorresponding grooves in the supporting-cylinder 68, which isprovided with a circumferential shoulder at one end, against which theprinting-form accurately fits when seated on its support. Thiscircumferential shoulder is not shown in the drawings; but it is similarto shoulder 23 on the primary printing-form. A marked rib 67 enters amarked groove in the cylinder 68, and these ribs and the circumferentialshoulder constitute guides, whereby the printing-form may be mounted inaccurate predetermined position both longitudinally and transversely onits support. Swung from the shaft 70, on which turns the maindistributing-cylinder 71, is the inking-frame 72, carrying inking- Thegear 71 on the hub of the cyl inder 71 drives the idle gear '75, whichmeshes with and drives the gear 76 on the cylinder 68. The gear iscarried on astud 75. The inking-frame 72is moved to and from thesecondary printing-form by the hand-shaft 75, which actuates the shaft76, carrying the gear 77, which meshes with the segmental gear 78 on theframe 72.

79 is the sliding dampening-frame carrying the dampening-rollers andoperated by the handwheel 80 on the shaft 81, which carries eccentrics62, working in boxes in the frame 79. The main ink-distributing cylinder71 is driven from the main shaft 9 by the wormsleeve 80, which mesheswith the gear 81 on the shaft 82, carrying the gear 83, meshing with thegear 84 on the upright shaft 85, this upright shaft 85 carrying thebeveled gear TIC 86, which meshes with the beveled gear 87 on thecylinder 71. The worm'sleeve is connected and disconnected with theshaft 9 by the clutch 88, operated from the shaft 89, which has thehand-shaft 90. The pressurearm 91 carries one of the sliding boxes forone end of the shaft 9210f the cylinder 68, and the pressure-arms 93 and94 carry the other boxes for the other end of the shaft 92, the arms 93and 94 being mounted upon the pivot 95 and held in place by the keeper96, which is operated by the hand-shaft 97. The lever 98 turns the shaft99, which carries the eccentrics 100, connected with and operating thepressure-arms.

The secondary printing-form 76 may be provided with a secondary set ofinking-rollers adapted to apply a suitable preserving body or ink to theprinting-form 76 after the latter has been converted into a lithographicor planographic printing-surface. In the particular machine shown in thedrawings these inking-rollers are mounted, arranged, and operated in thesame way as the inking-rollers in the frames already described. 101 isthe secondary inking-frame for these second ary inking-rollers. It isswung from the shaft 102, on which is loosely mounted the maininkdistributing cylinder 103, carrying a beveled gear 104, driven fromthe shaft 105, which is connected with and driven from the wormsleeve106 on the main shaft 9, the arrangement of the gearing being the sameas has always been described. The hand-shaft 107 actuates the shaft 108,operating the clutch 109 to connect and disconnect the screwsleeve 106from the shaft 9. The gear 110 on the stud 111 meshes with the gear '76and with the gear 112 of the cylinder 103, so that the main inkdistributing cylinder 103 drives the secondary printing-form 66. Thestuds 75 and 111 have square heads and are threaded in the main frame,so that the gears 110, carried thereon, can be drawn in toward the mainframe and out of mesh with their connecting-gears in order that each setof inkingrollers may operate separately in conjunction with thesecondary printing-form.

The hand-shaft 113 operates the shaft 114 to move the frame 101 to andfrom the secondary printing-form and in the same way and by the samemeans as the hand-shaft 75 and shaft 76.

The basic surface 3 preferably consists of a rigid backing 115, made ofmetal or other suitable material, and several sheets of thick paper 116,which are smoothly placed upon and secured to the backing, said backingand the sheets of paper constituting the transferbase, bearing on itsupper surface one or more designs. The bed 2 generally carries ayielding blanket or body, which may be made of rubberaud upon which thebasic surface rests when in its seat upon the bed. Of course the basicsurface may be constructed in any other suitable manner.

The conveying-surface 117 generally consists of a rigid backing 119,carrying on its upper surface a thin rubber sheet 120 and upon which thedesigns are to be imposed. Various constructions of theconveying-surface may of course be employed. Where rubber is used, asjust described, the designs imposed thereon by the primaryprinting-surface may be effaced and the same conveyingsurface may beused repeatedly. I might,how ever, stretch a sheet of paper on asuitable base, and said sheet of paper, when the design or plurality ofdesigns of the primary printing-surface have been imposed thereon, maybe bodily turned over upon the secondary printing-form. In such cases anew sheet of paper would necessarily be used in each separate operation,because the designs would not be effaceable from the paper.

The operation of the machine is as follows: The basic surface beingmounted in its preestablished seat on the bed 2 the bed is moved forwardby the motor 11 beneath the primary surface 19, which is lowered tobring the tooth 65 on the bed into mesh between the marked tooth on thegear 53. The bed is then moved forward with the basic surface andprinting-form in contact, suitable pressure being applied to thiscontact by the pressure-arms 26. The printing-form is thus made torotate in rolling contact with the basic surface, which imparts thedesigns thereon to the printing-form. If the designs for the basicsurface are on separate transfer-sheets, as shown in Fig. 4, thesetransfersheets will be turned over bodily upon the printing-form and thedesigns imposed upon said printingform. Thus the designs are imposedupon the primary printing-form in accurate predetermined position andwith reference to register. Bed 2 is then moved back out of the way andthe designs on the printing-form developed and made permanent. This maybe done by etching and rolling up after the lithographic manner or thedevelopment may be in accordance with any other method of treatment. Ifdesired, after the lithographic method of development has been resortedto the printing-form may be routed out or depressed. This development ofthe printing form may be done apart from the machine;

but the inking and dampening rollers carried in the frames 41 and 46,respectively, are intended in the machine shown in the drawings to beemployed in rolling up the printing-form, so that the printing-form maybe developed in the lithographic manner without withdrawing it from themachine. The primary printing-surface having been developed in suitablemanner, the basic surface 3 is then taken off of the bed 2 and theconveying-surface is mounted on the bed 2 in the prestablished seatprepared to receive it, which seat may be, and as shown in the drawingsis, the same as the seat for the basic surface 3. The bed 2 is thenbrought into contact with the primary printing-surface, the tooth 65being first entered in the marked reoess of the gear 53. As the bedmoves forward the design or designs of the primary surface are impartedto the conveying-surface in accurate predetermined position bothlongitudinally and transversely. The secondary printing-form 66 is thenbrought down upon the conveying-surface, the tooth entering the markedrecess in the gear 76, and the design or designs on the conveying-sunface are imparted to the secondary printingform. The bed 2 is then movedback out of the way, and the secondary printing-form is developed into aprinting-surface of the character desired. In carrying out thisdevelopment the inking and dampening rollers carried in the frames 72and 79, respectively, are employed in the manner well understood, theinking-frame 101 having been moved out of the way. After the secondaryprinting-surface has been developed it is then rolled up by means of thesecondary inking-rollers in the frame 101, which are employed to applyto the printing-surface a suitable preserving body in the manner and forthe purpose described in my pending application for Rolling-up machine,SerialNo. 709,877, filed March 21. 1899. This preserving body, which ispreferably a light-colored ink, serves to preserve the de sign,especially when the printing-surface is to be stored some time beforeuse and need not be washed off of the printi ng-surface before using theprinting-surface in the operation of printing. The dampening'rollers inthe frame 79 are used in conjunction with the secondary inking-rollers.Of course, if desired, the entire treatment of the secondaryprinting-form in converting it into a printing'surface and insubsequently applying the preserving body may be carried out apart fromthe machine. A series of duplicate secondary printing-surfaces may thusbe made from one primaryprinting-surface. Aseriesofsecondaryprinting-surfaces may also be made which have component designs adaptedto register in printing. In this latter casea series of primary surfaceswould be first made having component designs.

The primary and secondary printing-forms are driven by frictionalcontact with the basic surface or conveying-surface on the bed 2; but,if desired, they might be driven by some suitable form of gearing inaccurate unison with said surfaces.

In Fig. 7 is shown a machine similar to that illustrated in Figs. 1, 2,and 3, except that there are separate beds for the basic surface and forthe conveying-surface. 2 is the bed or support for the basic surface 3,and 2 is the bed or support for the conveying-surfaces 118. Thesesupports are moved back and forth by the screw-shaft 7, driven from themain shaft 9, and instead of having nuts per,- manently connected withthe screw-shaft 7, like the nut 8 of bed 2 in Fig. 1, they have threadedsplit sleeves 8 and 8", adapted to be connected and disconnected fromthe screwgearing.

shaft 7", so that the beds can be moved back and forth separately andindependently. The split sleeve 8 is shown in detail in Fig. 9. Theupper side of the sleeve is dovetailed in a transverse slideway 121,carried on the bed 2", and the two parts of the sleeve are made toclutch and unclutch the screw-shaft 7 by the screw-shaft 1.22. The bed2" has a tooth 65 and the bed 2 has a tooth 65*, these teeth enteringmarked recesses of the gears for the primary and secondary forms,respectively, for the same purpose as the tooth 65 on the bed 2.

In Fig. 8 the machineSis arranged so that the primary printing-form 19after havingreceived the design or designs from the basic surface 3 mayimpose the design or designs directly upon the secondary printing-form66 without the inter-mediation of aconveying-surface. The bed 2 is movedback and forth by the screw-shaft 7, and the primary printing-form isbrought down under pres sure upon the basic surface- After theprimaryprinting-form has been developed into a printing-s11 rface the primaryand secondary printing-forms are brought together in operating contact.For this purpose either one or both of the forms may be moved. As shownin Fig. 8, the secondary form 66 only is moved, being supported insliding boxes arranged to move back and forth in horizontal slideways inthe main frame by arms 123 and 124:, the latter of which is not shown.The outer ends of these arms are threaded and carry worm-wheels 125 and126, the latter not being sho wn, the arms passing through threadedhearings in the main frame. By rotating the hand-shaft 127 the arms 123and 124 are moved back and forth, so that the printing-forms may beseparated or brought together in contact under proper pressure. Thesecondary printing-form carries a gear 128, which meshes with an idlegear 129, which meshes with a gear 130 on ashaft 131, carrying aworm-gear 132, meshing with the Wormsleeve 133 on the driving-shaft. Thegear 129 is carried on the pivot of the toggle 134:, whose outer endsare pivoted, respectively, on the shaft 131 and on the shaft of thesecondary printing-form. The Worm-sleeve 133 is made fast and loose onthe drive-shaft by the clutch 135. By means of the toggle 134 and theconnecting-gearing the secondary form may be driven, notwithstanding itschange of position in the main frame. The primary and secondary formsmay be (.1 riven together by frictional contact or by suitable In orderthat they may be always brought into proper predetermined cooperatingrelation, the marked recess 136 on the support of the form 19 is broughtinto mesh with the marked teeth on the gearing 128. The bed 2 has atooth 65, adapted to enter a marked recess of the gear 136 on the support of the primary form, so as to provide a guide, with reference towhich the basic surface and primary printing -form may be brought intoaccurate predetermined cooperating relation. I

If desired, both the basic surface 3 and the conveying-surface 118 inFig. 7 and the basic surface 3 in Fig. 8 may be permanently secured toits supports. In this case the designs will be imposed upon the base ofthe basic surface while in place in the machine.

While I have shown the various features of the invention in the bestforms now known to me, it will be understood that various changes may bemade in the form and arrangement of the parts embodying the invention.So far as I am aware I am the first to provide a machine by means ofwhich a basic surface may be employed to impose a design or designs upona printing-form or primary printing-form and the said primaryprintingform be employed to impose its design or designs upon another orsecondary printingform, and I wish to claim the same herein broadly,also, in connection with guiding means whereby the design or designs maybe thus imposed upon the secondary printingformin accurate predeterminedposition and with reference to register.

The method in accordance with which and the mechanism whereby the designor designs are imposed upon the printing-forms 19 and 19 are shown anddescribed in the patents granted to me November2l, 1899, Nos. 637,555and 637,556. The method in accordance with which and the mechanismwhereby the design or designs are imposed upon the printing-forms 66 and62 are shown and described in the patents granted to me November 21,1899, Nos. 637,595, 637,596, and 637,599.
